Your fan heater won't stay on. The hair dryer cuts out mid-blow. The toaster trips and won't reset. Chances are the thermal fuse has done its job — opened the circuit to stop overheating — and now it's a one-time-use part that needs replacing. This Jaycar 77°C thermal fuse is the exact safety cutoff for 240V mains appliances. Swap it in, close the case, and the unit works again. Check your appliance's datasheet to confirm 77°C is the right threshold before you fit it
